This is the verse translation, not a definition of the individual word.
Those among you who pass away leaving behind widows, the widows should wait for four months and ten days [before remarrying]. When they have completed their waiting period, there is no sin on you concerning what they do for themselves[1] in a reasonable manner[2]. And Allah is All-Aware of what you do.
